A platform scale that weighs up to 660 lb and works out the total cost in the same step. Punch in a unit price and the LED screen reports weight, rate, and amount together, so a shipping desk or market stall never reaches for a separate calculator. Readings switch between pounds and kilograms for international parcels. The pole folds down to a 7-in profile that slides behind a counter or into a truck bed. A rechargeable 4V 4AH battery runs roughly 10 hours per charge and refills in 7 to 8 hours, while the adapter supports all-day plugged-in use.
